Hi Squeek123!
Good to have you popping back in and touching base with us.

It definitely sounds like there are some issues going on with your mom, even though you don't know if she is BPD. Have you ever read about a lot of the symptoms that are common with a BPD? If you go to the list on the right hand side of our C&H board, click on the one which says, "
Understanding BPD Behaviors" under the Lessons heading. An informative page opens up with a lot to read. You will be able to link to other articles from that page too and learn more about BPD.
Sometimes even though we read and study to learn, there is that craving within us surviving adult children to really
know that someone else sees it too, that we really aren't losing our minds, and yes, that something is wrong with them. We are not able to diagnose here, but we can definitely try to point you to be able to read and understand so you can ask questions about your parent and the life you grew up in. My mom was an uBPD, I am quite certain. There are also many other disorders that can accompany any BPD. Each BPD person is unique, although they do have many similarities. The DSM V has a good list of the criteria, and you'll find that list under the information I mentioned above.
Do you have anyone that you can talk to, a T that you see perhaps who can also help you along the way?
